Thirdhand smoke poses health risk

Secondhand smoke was already thought to be dangerous.

But now scientists are saying that third-hand smoke also poses a health risk.

Thirdhand smoke is the fumes that come off someone who has been smoking somewhere else.

Scientists are finding that the fumes can have a negative impact on our health, especially in children.

They said that the smoke and fumes left on clothing and in hair can cause asthma attacks.

"There's evidence now that thirdhand smoke is a risk factor in children like chronic ear infections and chronic respiratory infections," Dr. Norman Edelman of the American Lung Association said.

The American Lung Association says the best way to avoid this is to quit smoking.

But if that's not possible, smoke outside where the air is less concentrated and the smoke fumes are not as heavy and won't be left on clothing.
